[YuxinChou]

Hello Jeremy.
I have some prombles when i use OpenXmlBuilder.js, can you help me? Thank you.

First, How can I build a new OpenXnlBuilder.js with my template.docx or template.pptx?
------When I run ssh $ npm install
------Error:
5012 error Darwin 15.2.0
5013 error argv "/usr/local/bin/node" "/usr/local/bin/npm" "install" "phantomjs"
5014 error node v4.2.3
5015 error npm v2.14.7
5016 error code ELIFECYCLE
5017 error phantomjs@1.9.19 install: node install.js
5017 error Exit status 1
5018 error Failed at the phantomjs@1.9.19 install script 'node install.js'.
5018 error This is most likely a problem with the phantomjs package,
5018 error not with npm itself.
5018 error Tell the author that this fails on your system:
5018 error node install.js
5018 error You can get their info via:
5018 error npm owner ls phantomjs
5018 error There is likely additional logging output above.
------Where need phantomjs? i can't success when i try ' npm install ' many many times.

Second, I can success download a example.docx, but I fail in a example.pptx.
-------The download .docx Code: (success download)
// var db = new OpenXmlBuilder.DOCXBuilder(OpenXmlB64Templates.docx, title, created, creator);
// db.docLine(title, db.pStyle("Title"));
// db.docLine("Created " + created.toString(), db.pStyle("Subtitle"));
// db.docLine("HTML translated to native style", db.pStyle("Heading1"));
// // db.docContent(sampleHtml)
// db.docLine("HTML imported as chunk", db.pStyle("Heading1"));
// db.docChunk(sampleHtml)
// //var content = db.saveToBase64();
// var content = db.saveToBlob();
// saveAs(content, "example.docx");
--------The download .pptx Code: (fail)
// var pb = new OpenXmlBuilder.PPTXBuilder(OpenXmlB64Templates.pptx, title, created, creator);
// pb.contentSlide({"Title 1":"Delete this slide", "Subtitle 2" : "Delete this slide to ensure that contents are scaled to fit within the slides." }, 1);
// pb.contentSlide({"Title 1":title, "Subtitle 2" : "Created " + created.toString() }, 1);
// pb.contentSlide({"Title 1":"A question", "Content Placeholder 2" : sampleHtml}, 2);
// var pptcontent = pb.saveToBlob();
// saveAs(pptcontent, "example.pptx");
---------There is a error when run the second code "pb.contentSlide(..)....",
---------Error happen:
PPTXBuilder.prototype = {
.....
contentSlide: function(){
....
var shapes = slide.all("//p:sp");
....
}
....
}
.....
all: function() {
return this.xdoc.all.apply(this.xdoc, arguments);
},

--------- The ERROR " this.xdoc is undefined "

================================
Finally, can you help me in top 2 questions.
Or can you give me a html example to download a example.pptx with OpenXmlBuilder.js.
